Nicely done Keith (not Greg :D)! Great feather detail which is enhanced by the slightly ruffled look to them. I like the complimentary BG too. There is one hot spot above the bird's left leg, but otherwise like it a lot!
Lovely photo, colors are great, both bird and background. Nice eye as well. My only wish would be for a bit more seperation of neck from the body, but that is what the bird gave you. Really, very nice.
